1: Introduction The MPEG4000WA is a 4-channel multi-format MPEG-4, MPEG-2 or M-JPEG codec on a single PC/104-Plus form factor. The MPEG4000WA not only provides video compression but can also decompress and playback recordings from storage to display. Utilizing the 32-bit PCI architecture, the MPEG4000WA allows high quality real-time video and audio capture and compression from (up to) 4 concurrent NTSC or PAL video sources to disk while at the same time providing an additional path for incoming video to be Previewed on the host screen. The board also provides a text/graphics overlay, motion detection and digital water marking on all four channels. The high performance video image compression enables up to four MPEG4000WA cards to be fitted in a single PC/104-Plus system to provide up to 16 concurrent video streams to disk or across a network. AMP can provide custom configurations (subject to a minimum order quantity) for the MPEG4000WA. Please contact our Sales team (see A: Contacting Advanced Micro Peripherals, page 26) to discuss your requirements.

Introduction
MPEG4000WA Hardware Reference Manual
Functional summary
Signal sources The MPEG4000WA is designed to capture and record from up to four separate and unrelated video sources simultaneously. Each of the four video input channels of the MPEG4000WA features a video frame grabber and an audio digitizer. Each frame grabber contains a digital NTSC/PAL video decoder with a built-in 2-input video multiplexer. Therefore each channel of the MPEG4000WA is able to route in one-of-two analog video sources under software control and each video channel has an associated audio input. Up to 8 video sources can therefore be monitored using a single MPEG4000WA controller. A single audio input is associated with each live video channel.
Video digitization Composite NTSC or PAL video is input to the MPEG4000WA through the header VID1. The video is AC-coupled and fed to the on-board decoders of the individual frame grabbers. The video decoders automatically detect whether the incoming video signal is NTSC or PAL and generates the correct timing output signals. Each

Introduction
MPEG4000WA Hardware Reference Manual
video channel is first decoded to chrominance and luminance signals and then digitized by high speed 10 bit analog-to-digital (A2D) converters. The A2Ds output are passed to an internal digital video frame store controller where scaling, filtering, interpolation and channel re-timing operations are performed prior to encoding.
Digital video frame store controller The Quad Frame Store Controller (QFSC) contains 32 Mbytes of high speed SDRAM memory used as Frame Stores for each of the 4 digitized video channels. The QFSC co-ordinates the transfer of asynchronous video streams into the Frame Store and synchronous reading of all 4 channels to the encoding engine.
Real time live video encoding Digital video data streams from the frame store are managed by the video encoder engine where the video can be compressed as either MPEG-4, MPEG-2 or M-JPEG under the selection of a user API. Each of the video channels can be compressed to a separate video stream resulting in 4 separate video streams which can be written to disk (or LAN) as separate files. These streams can be either CIF resolution at full frame rate or full D1 at quarter frame rate. Alternatively, each of the channels can be regarded as occupying 1 quadrant of the picture frame thus allowing the four channels to be encoded to a single video stream or file. The encoding engine continuously encodes the video streams and uses the PC/104-Plus bus Master/Initiator interface to transfer data across the PCI bus to the system memory or disk. The measured latency for video compression is specified in the Technical Specifications section.
Video Preview The MPEG4000WA provides a secondary video path allowing the recorded video to be streamed to the graphics controller buffer of the host system for video previewing. The Preview output can also be used to view an alternate video source while recording other inputs. The Preview information is also available as a composite NTSC/PAL output suitable for driving a NTSC/PAL or RS-170 display device.
Real time MPEG-4 video decoding / playback The MPEG4000WA can also receive encoded video data over the PC/104-Plus bus and decode it to a raw digital video stream. This is fed into a high speed digitalto-analog converter and then encoded to analog composite video as either NTSC

or PAL. Additionally, the raw digital video stream can be displayed on the system VGA using the real time video preview functionality. Maximum image size of decoded video is 720x480 (NTSC) or 720x576 for PAL. Audio data which is part of the original recording is also decoded and played back in synchronisation with the video. In addition to playback to the host system display controller, the MPEG4000WA also provides a composite NTSC/PAL playback output suitable for directly driving a PAL/NTSC or RS170 display device.
OSD Graphics Overlay The MPEG4000WA has a bit-mapped graphic overlay feature which allows text and graphics to be overlaid onto the incoming video prior to recording. This is a useful feature for applying real-time annotation and labeling to Preview and video recordings. The MPEG4000WA provides various layers of overlay such as bitmap (720x480 for NTSC and 720 x 576 for PAL), box and 2D box array overlay and mouse pointer which can be overlaid on Preview and record paths independently. The box overlay layer allows up to 4 boxes (of any size and position) to be located on the screen using a palette of 64 colors and with 4 levels of alphablending. This feature can be useful for highlighting areas of text or key information. The mouse pointer layer enables a single pointer shape to be positioned anyone within the screen area. Video source information such as camera reference, location, time and date information can easily be overlayed on both preview and recordings. Information updates are only guaranteed to be completed within 2 frames (although in most cases, the update will be completed in less than one frame). Motion Detection and Event Triggers The MPEG4000WA supports automatic motion detection on a per channel basis. The ‘sensitivity’ of the motion detection can be set independently per channel. The board also allows ‘regions of interest’ to be defined by selecting or masking the macro-blocks (each macro-block is 16 x 16 pixels) of interest. Using the motion-detection feature, the MPEG4000WA can be operated in a ‘baby-sitting’ mode where recording is committed to disk only when scene motion event is detected, to make most efficient use of disk storage. Software for the MPEG4000WA allows recording of pre-trigger, on-trigger and post-trigger events.

MPEG4000WA Hardware Reference Manual
Watermark Authentication The MPEG4000WA features a powerful, patented watermarking algorithm for the authentication of recordings. Invisible watermarks are generated using a 128bit HMAC (Hash Message Authentication Code) and are embedded in the recording. This secure digital watermark enables any subsequent spacial or temporal tampering to be detected during video playback.
Host interface The MPEG4000WA has a full 32-bit PC/104-Plus (PCI Rev 2.1) host interface to the host computer. On board jumpers allow the MPEG4000WA to be configured for any of the 4 logical PC/104-Plus stack levels of the host computer.

3: Recording options Single channel recording The MPEG4000WA can perform recording of a single channel. In this mode, one channel is recorded at full D1 resolution at configurable frame rates.
Multi-channel recording modes The MPEG4000WA can operate in three modes when performing multi-channel recording. These are:
▪
Split channel mode.
▪
Merged channel mode.
▪
Multiplex channel mode.
In all of these modes there is the option to record only video or both video and audio.

720 x 480 (default) or 720 x 240 (option)
Split channel mode In split channel mode, video from the four frame grabber channels 1, 2, 3 and 4 are recorded as 4 separate and individual streams. In this mode, encoding parameters can be set for each channel on a per-channel basis allowing different settings for each of the channels. Each channel may be recorded with audio in the split channel mode. Each channel is recorded at CIF resolution.
Merged channel mode In merged channel mode, each of the channels is positioned in a quadrant of a full frame video and video encoding proceeds as if there were a single (composite) video frame. Thus the four channels are merged into the single frame (640x 480 for NTSC or 720 x 576 for PAL) and encoded to a single MPEG-4 file. NOTE: ONLY ONE AUDIO CHANNEL (SOFTWARE SELECTABLE) CAN BE RECORDED IN THE MERGED CHANNEL MODE.
Multiplexed channel mode In multiplexed channel mode, video from the 4 frame grabber channels 1, 2, 3 and 4 are recorded as 4 separate and individual streams. In this mode, encoding parameters can be set for each channel on a per-channel basis allowing different settings for each of the channels. Each channel may be recorded with audio in the Multiplexed Channel Mode. Each channel is recorded at full D1 resolution.

MPEG4000WA Hardware Reference Manual
Frame rates The default frame rates are 29.97fps and 25fps for NTSC and PAL respectively. However, for increased flexibility the frame rate can be selected simply by defining the number of inputs frames for each output frame (for example, 1/1 is full frame rate, 2/1 means 2 inputs for each output, i.e. ½ frame rate etc).
Frame type encoding The MPEG4000WA supports two frame encoding schemes within the encoder parameters to provide flexibility and optimize encoding efficiency and storage space. The default is I/P encoding, where both I and P frames are involved in the encoding. An alternative is I-only encoding. With I/P encoding, the I interval, which is defined as the number of P-frames between I-frames can be set to any number between 1 and 256.
Video Bit Rate control The Video Bit Rate can be set separately for each channel of compression (and hence storage efficiency) by using one of the two bit rate control schemes – Variable Bit Rate (VBR) or Constant Bit Rate (CBR). With VBR, the Quantization value (default of 5) can be set between 1 and 31 (for MPEG-4 & MPEG-2) or 1 and 100 (for M-JPEG) to optimize efficiency for a particular application (with 1 being highest quality). This mode strives to keep the quality constant and will change the bit rate accordingly. The default bit rate for CBR is 1Mbit/sec. However, the actual bit rate may change by +/-10% around the set figure until the system ‘settles down’. CBR therefore does not guarantee that the bit rate in practice will be exactly as set – the MPEG4000WA simply does its best to achieve the set CBR figure. The real life bit rate when in CBR mode will depend on the incoming video, motion and other environmental factors. It may be worth finding out experimentally the optimum CBR setting for a particular application environment in order to make the best use of CBR configuration.

Hints for reducing bit rates There are four ways that you can reduce the bit rate and hence optimize storage:
▪
Reduce the picture size
▪
Increase the quantization value
▪
Reduce the frame rate
▪
Increase the I picture interval
NOTE: THESE OPTIONS MIGHT NOT BE AVAILABLE UNDER CBR. IN CBR, QUANTIZATION VALUE IS CONTROLLED BY THE MPEG4000WA TO MEET THE SET BIT RATE ONCE THE PICTURE SIZE, FRAME RATE AND I PICTURE INTERVAL ARE FIXED.
